DOMESTIC HEATER.

Specification of Letters Patent.

Patented June 4, 1918.

Application filed April 12, 1918. Serial No. 228,111.

To all whom it may concern:

Be it known that I, HENRIETTE BOURSIER, citizen of the Republic of France, residing at New York city, New York, have invented certain new and useful Improvements in Domestic Heaters, of which the following is a specification.

This invention relates. to domestic heaters of the type in which the water to be heated is contained in a jacket surrounding the hearth; and it comprises, briefly, animproved heater of the character indicated which will occupy but small space, is simple in its construction and inexpensive to manufacture, and in which wood, coal, sweepings and refuse may be burned as fuel, the water being heated in an extremely short time to a relatively high temperature.

An embodiment of the invention is illustrated in the accompanying draw1ng,-in which Figure 1 is a vertical section of the improved heater, with parts in elevation,

and Fig. 2 a horizontal section on line 2--2,

ferent directions. The upper or outlet pipe 15 has its inner end provided with an inlet Fig. 1.

Referring more particularly to said drawing, 1 designates the base, to which the grate or hearth 2 is fixed and on which is mounted the cylindrical water jacket containing the water to be heated. This jacket consists of outer and inner vertical shells 3 and 4, arranged in spaced, concentric relation to each other and closed at their tops by the covers 5 and 6, as shown. The chimney 7 extends through both covers, and the two shells are connected together adjacent their upper ends by the strip 8, which is located in the space between said shells and forms the top of the jacket. Water is supplied to the jacket at the lower portion thereof by way of the inlet pipe 9, and, after having been heated in the manner hereinafter described, leaves the top of the heater through the outlet pipe 10.

Within the interior of the heater is mounted a hollow, sheet metal cone 11, the fiat bottom or base of which is disposed above and parallel with the grate 2, and has a diameter somewhat less than that of the inner j acket wall "or shell 4, thus providing an annular passage or channel between the base of the cone and the said shell through which the flames and products of combustion ofthe; burning fuel on the grate can pass and com-* pletely envelop the cone.

The water to be heated is supplied to the cone through an inlet pipe 12, which pr0- Adjacent its free end, there opens into said pipe 12the lower end of a vertical con necting pipe 14, thevv upper, end of,which opensinto a horizontal outletpipe 15,,the latter projecting outwardly from the upper portion of thecone into the jacket and is likewise fastened to the shell 4. The connecting pipe 14 is formed intermediate its ends with a plurality of superposed pairs of openings 16, which are arranged in staggered relation, as shown, or in some other similar manner, so that they open through the circumferential wall of the pipe in difopening 17 for the water in the cone.

In operation, water enters the bottom of the jacket through the inlet 9, and circulates in the jacket'until it reaches the cone inlet pipe 12, whereupon it flows into the cone and. as above stated, is discharged against the inclined wall of the cone and is deflected laterally to either side. Some of the water entering the pipe 12 ascends, however, through the connecting pipe 14, instead of flowing through the outlet end 13, and is discharged into the cone through the openings 16. In consequence, the water, as it rises in the cone, has imparted to it to a greater or less extent, a spiral or whirling motion, due to the jets of water ejected laterally through the openings 16, so that the water is caused to flow through the cone around and against the walls thereof, against which the flames and products of combustion directly contact, as previously explained. The opening 17 in the pipe 15 acts, an inlet for the water, which flows therethrough into said pipe and thence into the jacket, the passage of the water through said opening being facilitated, to some extent at least, by the suction or drag created by the water flowing through the connecting pipe 14; the highest pair of openings 16 ma; also, and possibly does, exert a similar actlon, though the lower pairs obviously act however, as

passes from the jacket, by way of-the pipe 10, to the Owing surroun combustion, the heating of the water in the cone takes place very. rapidly, and the circulation is more intense than that which occurs in the lower portion "of-the jacket" where the water is cooler. Also,vsince the baseofthecone is disposal-directly above the grate; a comparatively small {quantity only of fuel is needed to effect the heating, and scrap paperj." *sweepings, and other waste,-{with{the-additionof a little wood, maybe utilized as fueljthereby avoiding the danger ordinarily present in oil-burning l s r, v N v point where it is dlfa.WI10fi'.v= to the fact that the cone is entirely invention A' watr heater,v comprising, in combina tio'n, bat a gratesecured'thereto'; a water jacketmounted on said base and. encircling sa1d'grate; a water supply pipe opening into the lower portionfiof the jacket a discharge pipe" for the heated water leading from the topw 'f the jacket a heating cone disposed the acket above th'e 'water supply Copies-"of thispatent niay "be pbtai'ned for ed by the flame and products iofv pipe and having its base directly overhanging-the grate and of a diameter which is appreciably less than that of the inner wall of the jacket to provide an annular channel between said inner wall and said base, thereby to enable the flame and products of combustionzto completely envelop the cone,- said cone having its axis inclined toward said inner shellg inlet and outlet pipes projecting outwardly from the interior of the. cone adjacentthe base and vertex thereof, respectively, into the interior of said jacket, the inlet pipe having its free ,end open to per'n'iit water to flow therethrough into the cone, and the outlet pipe having an opening in it s 'inner end to 'adrnit the water thereinto; and a vertical pipe within the cone connecting said inletandpoutlet pipes and through which .a portion ofthe water passing through the inlet pipe is caused to flow,
